Did a factory reset yesterday, added all my mains-powered devices and let the Heart rest for the night.
Just now, I tried to add a Fibaro TRV, was too slow with triple clicking, so the inclusion failed,
I pressed “back” until the wizard was closed.
After that, the controller was unresponsive again.
Rebooted and then found a new loose node.
Additionally, yesterday it happened several times that I had to confirm the security key 2-3 times during the inclusion process or had to name and place the new device more than one time after the interview was done.
Meanwhile I am only using S0 security.
There really seems to be something wrong with the Z-Wave package.
